Title: Improvements in and relating to emergency release mechanism for clothes wringers
IPC: D06F45/18
Filed: 1950-10-31
Abstract: 681,773. Wringers. BRITISH THOMSONHOUSTON CO., Ltd. Oct. 31, 1950. [Nov. 3, 1949] No. 26549/50. Class 138 (ii). A clothes wringer comprises a wringer head on which a frame is swingably mounted, wringer rolls journalled within the frame driven through gearing of the type biased to neutral, gear shift mechanism including a shift actuator, a detent sleeve therefor and handle means for operating the actuator, a detent supported by a member on the head and engaging with the sleeve for releasably securing the gear shift mechanism in driving position, means for withdrawing the detent when the frame is displaced with respect to the head comprising an angular member pivotally connected to the detent having a forked base resting on the head, the base providing a fulcrum on either side of the detent axis and means interconnecting the frame and a portion of the angular member to rotate the latter about a base fulcrum when the frame is displaced to cause release of the detent. In the arrangement shown, a winger frame 3 is pivotally supported on a head 1 by means of a channel shaped bracket 11 in which springs 14 maintain operative relationship between the frame and head and ensure driving engagement between a roll shaft 16 and a sprocket 17. The sprocket 17 is driven through a gearing arrangement of known type from a shaft 5 in either direction, in dependence upon the rotation of a shaft 19 by means of a handle 23. The shaft 19 is biased to a neutral position to disengage the gearing from sprocket 17 by a spring 24 located on the shaft and secured at its ends between a sleeve 20 and a fixed collar 21. A spring-loaded detent pin 28 co-operates with notches 27 on the sleeve 20, the notches establishing operating positions of the handle 23, and the pin 28 is pivotally connected to a release actuator 33, the upper end of which is engaged by a forked arm 32 rigid with the bracket 11. The actuator 33 includes a forked base 34 which rests on a bracket 29 and straddles the pin 28 whereby angular displacement of arm 32 enforces rotation of the actuator about either of its edges to lift the pin 28 and release the shaft 19 for return to the neutral position under the action of spring 24. Specification 673,021 is referred to.

Abstract: 780,240. Axial flow compressors and turbines. EGGLETON, F. Sept. 19, 1955, No. 26689/55. Classes 110 (1) and 110 (3). An axial flow compressor or turbine of two or more stages comprises a casing having a smooth internal surface and in the case of a turbine with a ring of nozzle blades at the inlet end and a rotor having a series of blades spaced around its circumference in which each adjacent pair of blades define a continuous generally axial passage through the annular space between the rotor and casing in which, in a compressor, the working fluid is alternately accelerated or retarded in a tangential direction or, in a turbine, retarded in the tangential direction in the first stage and then alternately accelerated and retarded in the tangential direction. The blades are formed by a continuous series of aerofoil-shaped portions positioned on alternately reversed curved axes or camber lines. The turbine, Fig. 2, consists of a series of nozzle vanes G1 and a rotor having the passages formed by the blades F1.

Abstract: 987,681. Rotary pumps and motors. PLESSEY CO. Ltd. July 14, 1961 [Aug. 2, 1960], No. 26692/60. Heading F1F. A rotary displacement pump (or motor) has at least one rotor 2 (e.g. two meshing gears) and the pressure-loaded bearing housings 8 are of a material e.g. high-expansion aluminium alloy, which is of higher coefficient of thermal expansion than that of the pump housing e.g. low-expansion aluminium allow, such that, when the housings 8 are held fixed centrally of their length by friction resulting from radial load, the sealing surfaces of side plates 6, 7 remain in contact with the rotor 2 at all variations of temperature within the operating range. There are bronze bearing sleeves 13 and filler sleeves 14, which are of the lowexpansion 36 % nickel-steel alloy known as "Invar" (Registered Trade Mark) so that the total radial expansion of the elements 8, 13, 14 equals that of the rotor 2. The housings 8 are loaded by pump delivery pressure supplied between O-ring seals 10, 11. 1.

An electrically-driven drum for driving a conveyer or a pulley is cooled by passing fluid through the inside of the stator. Outer drum 1 is driven through gearing 34 from an inner drum 10 carrying a rotor 24. Stator 20 is mounted on a sleeve 56 fitting tightly on shaft 8, and the stator winding 22 is energized through leads which pass through a bore at one end of shaft 8. The other end of the shaft is also hollow and the bore 51 communicates with a first helical channel 54 between the shaft and the sleeve 56. A second helical channel 61 runs parallel to the first and communicates with it at the end further from bore 51. Channel 61 communicates with a tube 70 passing through the centre of bore 51 and sealed from it by seal 71. Fluid, such as water, passes from inlet 73 through the channels to outlet 74. Alternatively, a single channel may be used and the bore 51 extended to the other end of stator 20. The channel or channels may zig-zag round the shaft instead of running helically. The channels may be constructed as described in Specification 883,827.

Abstract: 445,994. Boiler &c. cleaners. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London.-(Assignees of Howse, C. L., and Bowers, F.; 10340, Oakland Avenue, Detroit, Michigan, U.S.A.) Sept. 27, 1935, No. 26821. Convention date, Sept. 28, 1934. [Class 99 (ii)] The nozzle 50 of a boiler &c. cleaner blower element which is normally housed in a wall box 28 is rotated and also moved to projected and retracted positions by a motor 70 which is started by hand but is reversed and stopped automatically by a switch 98. This switch 98 is actuated by a member 93 which is fixed on a rod 91 slidably mounted in bearings 90 and is shifted first to the left to reverse the switch and motor when a nut 85 engages a stop 92 on the left-hand end of the rod 91 and then to the right to stop the motor when the nut 85 engages a corresponding stop 92 at the other end of said rod, the nut 85 being non-rotatably threaded on a screwed rod 80, rotated by a shaft 72 driven by the motor, to move in synchronism with the blower nozzle. The nut 85 carries an indicating member 89, and the rod 91 may be shifted manually to effect a reversal of the motor before the nozzle reaches its fully projected position by a lever 99. The nozzle is formed with two opposed discharge orifices 53 and is carried on the end of a tube 51 which is slidably secured by a key 56 to an outer tube 52 rotatable by a slidable worm wheel 63 in engagement with a worm 73 on the rotating shaft 72. The other end of the tube 51 is provided with a nut 54 engaging a tube 43 which is itself slidably mounted by a non-rotatable bearing 40 on the screwthreaded cleaning fluid supply pipe 35. This arrangement is such that during each rotation of the shaft 72 the nozzle 50 will be rotated once and also moved axially a distance equal to twice the pitch of the threads on the pipe 35 and tube 43. The Specification also describes a slightly modified construction of blower element having a pointer moving over a quadrant - shaped plate for indicating the position of the nozzle.
